Description

Technical Field

[0001] This utility model relates to a visual inspection variable distance mechanism at both ends of a module, belonging to the technical field of battery cell module production line. Background Technology

[0002] In the battery cell production process, attaching insulating covers to the battery cell modules is a crucial step. During this process, a vision inspection mechanism consisting of a camera and a light source performs visual inspection of the battery cell modules. This mechanism is set up at the insulation cover attachment station and fixed to a corresponding support. The battery cell modules are pressed and fixed from the top by a clamping mechanism. The vision inspection mechanism positions the battery cell modules for the insulation cover attachment, and then a robot attaches the insulation cover. However, existing vision inspection mechanisms have fixed cameras and light sources. When the battery cell modules to be insulated are large or small, the distance between them and the camera is small or large, reducing the inspection accuracy. Therefore, they are not suitable for producing battery cell modules of different sizes and have poor versatility. Summary of the Invention

[0003] The purpose of this utility model is to provide a visual inspection variable distance mechanism at both ends of a module, which solves the technical defect in the prior art where the position of the visual inspection mechanism is fixed when the battery cell is covered with an insulating cover, making it unsuitable for the production of modules of different sizes and specifications, and resulting in poor versatility.

[0004] To solve the above problems, the technical solution adopted by this utility model is: a visual inspection distance-changing mechanism at both ends of a module, including a linear module, a module moving plate, a camera, and a light source. In use, the linear module is mounted on a fixed object. The module moving plate is mounted on the linear module and driven to move by the linear module. There are one or more cameras and light sources, both mounted on the module moving plate and moving synchronously with it, used to adjust the distance between the camera / light source and the battery cell module in use. In this utility model, the camera and light source are mounted on the module moving plate, and the linear module drives the module moving plate to move, allowing the camera and light source to move towards or away from the battery cell module according to its specifications. This makes it suitable for detecting insulating covers on battery cell modules of different specifications, improving the versatility of this utility model.

[0005] As a further improvement of this utility model, it also includes a positioner plate, which is disposed on the module moving plate, and its position on the module moving plate can be adjusted along the moving direction of the linear module. A light source is mounted on the positioner plate, and one camera is mounted on each positioner plate. By setting the positioner plate, this utility model allows for further adjustment of the distance between the camera and the battery cell module when the module moving plate moves to its maximum stroke position, thereby further improving the versatility of this utility model.

[0006] As a further improvement of this utility model, the positioner plate includes an upper positioner plate unit and a lower positioner plate unit. The lower positioner plate unit is disposed on the module moving plate and its position can be adjusted along the moving direction of the linear module. The upper positioner plate unit is disposed on the lower positioner plate unit and its position can also be adjusted along the moving direction of the linear module. The camera is mounted on the lower positioner plate unit, and the light source is mounted on the upper positioner plate unit. The positioner plate in this utility model is composed of an upper positioner plate unit and a lower positioner plate unit, wherein the positions of the upper positioner plate unit and the lower positioner plate unit are relatively adjustable, thereby adjusting the distance between the camera and the light source as needed.

[0007] As a further improvement of this utility model, two through-hole grooves are formed along the length of the lower position plate unit. The lower position plate unit is mounted on the module moving plate using lower bolts that pass through the lower slots and are threaded into the module moving plate. Loosening the lower bolts allows the lower position plate unit to move along the length of the lower slots, while tightening the lower bolts presses the lower position plate unit firmly onto the module moving plate. This utility model allows the lower position plate unit to be detachably mounted on the module moving plate using lower bolts. By loosening and tightening the lower bolts, the lower position plate unit can be moved or fixed to the module moving plate.

[0008] As a further improvement of this utility model, an upper waist-shaped groove is formed on the upper position plate unit along its length direction. The upper position plate unit is installed on the lower position plate unit by an upper bolt that passes through the upper waist-shaped groove and is threadedly engaged with the lower position plate unit. Loosening the upper bolt allows the upper position plate unit to move along the length direction of the upper waist-shaped groove, while tightening the upper bolt presses the upper position plate unit firmly onto the lower position plate unit. This utility model allows the upper position plate unit to be detachably installed on the lower position plate unit by the upper bolt. By loosening and tightening the upper bolt, the upper position plate unit can be moved or fixed on the lower position plate unit.

[0009] As a further improvement of this utility model, a light source connecting sheet metal is fixed on the upper positioning plate unit, and the light source is detachably mounted on the light source connecting sheet metal. This utility model, by providing a light source connecting sheet metal, facilitates the detachable mounting of the light source on the upper positioning plate unit.

[0010] As a further improvement of this utility model, there are four positioner plates, evenly distributed on the module moving plate. There are two light sources, both elongated in shape. One light source has its two ends detachably mounted to the upper positioner plate units of the two positioner plates located at one end of the module moving plate, and the other light source has its two ends detachably mounted to the upper positioner plate units of the two positioner plates located at the other end of the module moving plate. This utility model uses elongated light sources to illuminate the battery cell module during use, resulting in a more uniform light distribution on the battery cell module and facilitating visual inspection of the battery cell module by the camera.

[0011] As a further improvement of this utility model, it also includes two linear slide rails, which are located on both sides of the linear module. The two linear slide rails are mounted on a fixed object and are parallel to the linear module. The module moving plate slides in cooperation with the two linear slide rails. This utility model facilitates the movement of the module moving plate on the fixed object by setting the linear slide rails to cooperate with the module moving plate.

[0012] As a further improvement of this utility model, in use, the visual inspection variable-distance mechanisms at both ends of the two modules are respectively arranged on both sides of the module pressing mechanism, and the camera and light source are both arranged facing one side of the module pressing mechanism. The visual inspection variable-distance mechanisms at both ends of the two modules of this utility model simultaneously perform visual inspection of the battery cell module from both sides, improving the visual inspection efficiency of the battery cell module.

[0013] As a further improvement of this utility model, in the use state, the visual detection variable distance mechanisms at both ends of the two modules are symmetrically arranged on both sides of the module pressing mechanism.

[0014] In summary, the beneficial effects of this utility model are: by moving the module moving plate, the camera and light source can move closer to or further away from the battery cell module according to the specifications of the battery cell module during use, thus making it suitable for visual inspection of battery cell modules with insulating covers of different specifications, and improving the versatility of this utility model.

[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0020] like Figure 1 and Figure 2 The visual detection variable-distance mechanism at both ends of the module shown is, in use, respectively positioned on both sides of the module pressing mechanism 12, and symmetrical about the module pressing mechanism 12. The camera 3 and light source 4 of both visual detection variable-distance mechanisms at both ends of the module are both positioned facing one side of the module pressing mechanism 12. For example... Figure 3 As shown, the module pressing mechanism 12 of this utility model includes a bracket and two pressing units mounted on the bracket. The bracket includes two support units and a rectangular support frame 13 mounted on the two support units. Each support unit includes a support beam 14 and two support columns 15. The two ends of the support beam 14 are fixedly connected to the top ends of the two support columns 15, respectively. The support beams 14 of the two support units are parallel. The two ends of the support frame 13 are fixedly connected to the middle of the support beams 14 of the two support units, respectively. Both pressing units are mounted on the support frame 13. Each pressing unit includes a fixing plate 16, at least one guide rod 17, a pressure plate 18, and a pressing cylinder 19. The fixing plate 16 is fixed to the support frame 13. Both the fixing plate 16 and the pressure plate 18 are rectangular plates. There are four guide rods 17. The bottom ends of the four guide rods 17 are fixedly connected to the pressure plate 18. The top ends of the guide rods 17 pass through the fixed plate 16 and are connected to the fixed plate 16 by a straight bearing. The cylinder body of the pressing cylinder 19 is fixed on the fixed plate 16. The piston rod of the pressing cylinder 19 passes downward through the fixed plate and is connected to the pressure plate 18. The piston rod of the pressing cylinder 19 extends or retracts to drive the pressure plate 18 to move up and down reciprocally. The two visual detection pitch-changing mechanisms at both ends of the module are symmetrically arranged on both sides of the support frame 13. In the use state, the AGV trolley equipped with the battery cell module moves from between the two support columns 15 to the bottom of the pressing unit. The piston rod of the pressing cylinder 19 extends, pushing the pressure plate 18 to move downward and pressing the battery cell module on the AGV trolley.

[0021] like Figure 1 and Figure 2As shown, the visual detection distance-changing mechanism at both ends of the module in this utility model includes a linear module 1, a module moving plate 2, a camera 3, and a light source 4. The linear module 1 is installed on a fixed object in use. The linear module 1 in this utility model can be directly fixed to the ground or set on a support frame fixed to the ground. The module moving plate 2 is installed on the linear module 1 and is driven to move by the linear module 1, so that the module moving plate 2 can move toward or away from the module pressing mechanism 12. In this utility model, there is at least one camera 3 and one light source 4. Both the camera 3 and the light source 4 are installed on the module moving plate 2, and the camera 3 and the light source 4 can move synchronously toward or away from the module pressing mechanism 12 as the module moving plate 2 moves, which is used to adjust the distance between the camera 3 and the light source 4 and the battery cell module on the module pressing mechanism 12 in use.

[0022] like Figure 1 and Figure 2 As shown, this utility model is provided with a position plate 5 for mounting a camera 3 and a light source 4. The position plate 5 is set on the module moving plate 2. The projection of the position plate 5 on the horizontal plane is rectangular, and its length direction is the same as the moving direction of the linear module 1. The position of the position plate 5 on the module moving plate 2 can be adjusted along the moving direction of the linear module 1. The light source 4 is mounted on the position plate 5, and one camera 3 is mounted on each position plate 5. The positioner plate 5 in this invention includes an upper positioner plate unit 6 and a lower positioner plate unit 7. The projections of both the upper and lower positioner plate units 6 and 7 on the horizontal plane are rectangular. The lower positioner plate unit 7 is disposed on the module moving plate 2 and its position can be adjusted along the moving direction of the linear module 1. After the position is adjusted, it can be fixed on the module moving plate 2. The upper positioner plate unit 6 is disposed on the side of the lower positioner plate unit 7 away from the module pressing mechanism 12, and its position can be adjusted along the moving direction of the linear module 1. The camera 3 in this invention is installed on the side of the lower positioner plate unit 7 close to the module pressing mechanism 12, and the light source 4 is installed on the upper positioner plate unit 6. Since the position of the upper positioner plate unit 6 can be adjusted on the lower positioner plate unit 7, this invention can adjust the relative position of the light source 4 and the camera 3 by adjusting the relative position of the upper positioner plate unit 6 and the lower positioner plate unit 7, thereby changing the distance between the light source 4 and the camera 3.

[0023] like Figure 1 and Figure 2As shown, in order to adjust the position of the lower position plate 7 on the module moving plate 2, the present invention provides two through-holes shaped grooves 8 on the lower position plate unit 7 along its length direction (i.e., the direction in which the linear module 1 drives the module moving plate 2 to move). The lower position plate unit 7 is detachably installed on the module moving plate 2 by two lower bolts that pass through the lower waist-shaped grooves 8 and are threadedly engaged with the module moving plate 2. When the lower bolts are loosened, the lower position plate unit 7 can be moved along the length direction of the lower waist-shaped grooves 8, thereby adjusting the position of the lower position plate unit 7 on the module moving plate 2. When the lower bolts are tightened, the lower position plate unit 7 can be pressed onto the module moving plate 2 to fix the lower position plate unit 7 and the module moving plate 2. This utility model provides an upper waist-shaped groove 9 along its length on the upper position plate unit 6. The upper waist-shaped groove 9 is parallel to and staggered with the lower waist-shaped groove 8. The upper position plate unit 6 is detachably installed on the lower position plate unit 7 by an upper bolt that passes through the upper waist-shaped groove 9 and is threadedly engaged with the lower position plate unit 7. When the upper bolt is loosened, the upper position plate unit 6 can be moved along the length of the upper waist-shaped groove 9, thereby adjusting the position of the upper position plate unit 6 on the lower position plate unit 7. When the upper bolt is tightened, the upper position plate unit 6 can be pressed onto the lower position plate unit 7 to fix the upper position plate unit 6 and the lower position plate unit 7.

[0024] like Figure 1 and Figure 2 As shown, to facilitate the installation of the light source 4, a light source connecting sheet metal 10 is fixed on the upper position plate unit 6. The light source 4 is detachably installed on the light source connecting sheet metal 10. The bottom of the light source connecting sheet metal 10 is fixedly connected to one side of the upper position plate unit 6. A through hole is provided on the top of the light source connecting sheet metal 10 for connecting the light source 4. In this invention, there are four position plates 5, which are evenly distributed on the module moving plate 2. There are two light sources 4, which are elongated. The two ends of one light source 4 are detachably installed on the upper position plate unit 6 of the two position plates 5 located at one end of the module moving plate 2 via the light source connecting sheet metal 10. The two ends of the other light source 4 are detachably installed on the upper position plate unit 6 of the two position plates 5 located at the other end of the module moving plate 2 via the light source connecting sheet metal 10.

[0025] like Figure 1 and Figure 2As shown, in order to improve the stability of the movement of the module moving plate 2, this utility model is provided with two linear slide rails 11. The two linear slide rails 11 are located on both sides of the linear module 1. The two linear slide rails 11 and the linear module 1 are installed on the same fixed object and are parallel to the linear module 1. A slider (not shown in the figure) is installed at the bottom of the module moving plate 2. The slider is slidably engaged with the two linear slide rails 11. The sliding engagement between the slider and the linear slide rails 11 allows the module moving plate 2 to slide linearly on the linear slide rails 11 under the drive of the linear module 1.

[0026] Unless otherwise specified in the above description, all parts are existing technology or can be implemented using existing technology. Furthermore, the specific embodiments described in this utility model are merely preferred embodiments of the invention and are not intended to limit the scope of this utility model. That is, all equivalent changes and modifications made within the scope of this utility model patent should be considered within the technical scope of this utility model.
